. No. 929,674. Specification of .means,t associated with the (jet nozzle, for

dividing or breaking'up the outer skin of the et, sothat 1t issues from the orifice 1n the form of an envelop of separated and partly scattered water particles surrounding an interior solid and compact core. 7 The gas or other fluid to be moved, surrounding the jet, mixes, readily with the separated. 'ater particles of the outer envelop and becoming entrained therein, is discharged through the exhaust, while the ener y of the jet as a whole and the force of the ischarge is maintained by the momentum of the solid core of water passing through the chamber,

Thus an .eifective. entrainment and exhaustion of the gas is accomplished;while the energy of the jet is not materially influenced by the slight disturbance ,of its skin, which produces the entraining envelop.

In the accolnpanying drawings 'l igure' 1- represents in central longitudinal section a water jet steam -c ndens,er of a known type and Figs. 2 and 3 represent, in enlarged longitudinal and transverse sections,

. the jet" nozzles which embody this invention Fig. l represents 1n section another form of asplrating apparatus having a.

single jet'nozzle employing this invention and Fig. 5 is an enlarged detail plan of the interimot su -h nozzle showing the ribs or grooves therein; Figs. 6 and are respectively longitudinal and transverse sections of a developed form of the invention.

leterriug to Figs. 1 to 3, the reference numeral 1 represents the casing of a chamber for the steam or other fluid to be moved, which has the inlet for 'such fluid at 2 and the discharge outlet at 3. The water head 4 which forms the closure to the top of the chamber, .is perforated with a number of water jet nozzles 5, which discharge into the chamber and within a perforated separat iug tube 6 therein.

toward the end of the separating tube where they me'et and pass together out ofthe" tail tube 3'. As, shown more clearly in' tlfe enlargedviews of Figs. 2 and 3, each jet nozzle is 'somewhattapered toward its orifice, and on its interior wall it is provided with a.

which serve to divide or break up 'the surface or skin of the water column passing envelop above referred to, while the central getremains as a solid core, the momentum of which maintains the force of the discharge. The said ribs or grooves may extend to the extreme end ofjthe nozzle as shown or they may terminate somewhat in advance of that pointi sage 10, has but a single jet nozzle, the niternalfribs'or grooves 11 of which are spi- -rally disposb'd so asto produce more or less of awhirling motion in the entrainin'g envelo while. the interior solid core passes straight tothe'dischargeinlet. The ribs and grooves of this form ofthc invention termi;

but they may extend down to the the-preceding form, if desired.

In the nozzle shown in section in Figs. (3 andi7, an inner concentric nozzle or ring 12 is located within themain nozzle orifice 13, as a rnda ns for separating the envelop from theeore and whereby also, a smooth Or polend as in vclop issues from the annular space between the two nozzles and issubdivided-and broken up by means of a series of substantially longitudinal partitions 'or vanes disposed therein. These vanes maybe )arallel with the axis of the nozzle, like the ribs of Figs. 1 to 3,..bnt they have preferably a slight pitch as shown, in order to produce whirling motion of the envelop.

Having described my invention',-' what I claim and desire to secure by United States Letters Patent is: 1

1. In water jet apparatus, the 'conibination with achamber containing fluid tel-be moved,"of a nozzle adapted to discharge a solid-core actuating water jet into said. chamher to move said fluid and provided with .1 r the gets from the several nozzles convergeeircumferential series of ribs or grooves through it and thus produce the entraining In the apparatus ofFigs. land 5, the chamber 8 with its inlet 9 and exhaust pasnate slightly above the end of the nozzle,

portion'of the column of water in each 'ater ish'ed discharge opening may be provided for the latter. The water forming the enmeans for issuing an entraining envelop. of separated or scattered water particles surrounding the said core:

2. In waterqet apparatus, the combination with a chamber containing fluid 'to'be moved, of an actuating water-jet nozzle dis- 1 charging ing within its orifice a circumferential series of ribs or grooves adapted for producing an entraining envelop-for the solid core of the I 4. In water-jet apparatus,a tapered water-- 2o jet nozzle provided with a series of circum- "ferentially disposed ribs adapted for acting upon the jetand producing an entralning envelop around the central portion thereof.

5. In water-jet actuating apparatus, a

water-jet nozzle provided with an annular series of interna ribs, terminating in ad- 1 vance of the orifice of said nozzle and adapted to produce an entraining' envelop -for the solid core of the jet. k

6. In water-jet apparatus, a'water-jet nozzle provided with an interior circumferential series of internal, spirally arranged ribs,

adapted for issuing an entraining envelop 7 around the solidcore' ofthe jet.

7 In water- Jet actuating apparatns, a water nozzle comprised of concentric orifices,

the outer of said orificesbeing provided with substantially longitudinal ribs adapted for producing an entraining envelop of Water for the jet issuing from the' inner orifice.

Iii-testimony whereof, -I have signed my name to the specification in the presence of two subscribing witnesses. 4
